# {{< icon "fab fa-windows" >}} Microsoft Azure Blob Storage
|
||
|
||
Paths are specified as `remote:container` (or `remote:` for the `lsd`
|
||
command.) You may put subdirectories in too, e.g.
|
||
`remote:container/path/to/dir`.
|
||
|
||
## Configuration
|
||
|
||
Here is an example of making a Microsoft Azure Blob Storage
|
||
configuration. For a remote called `remote`. First run:
|
||
|
||
rclone config
|
||
|
||
This will guide you through an interactive setup process:
|
||
|
||
```
|
||
No remotes found, make a new one?
|
||
n) New remote
|
||
s) Set configuration password
|
||
q) Quit config
|
||
n/s/q> n
|
||
name> remote
|
||
Type of storage to configure.
|
||
Choose a number from below, or type in your own value
|
||

|
||
y) Yes this is OK
|
||
e) Edit this remote
|
||
d) Delete this remote
|
||
y/e/d> y
|
||
```
|
||
|
||
See all containers
|
||
|
||
rclone lsd remote:
|
||
|
||
Make a new container
|
||
|
||
rclone mkdir remote:container
|
||
|
||
List the contents of a container
|
||
|
||
rclone ls remote:container
|
||
|
||
Sync `/home/local/directory` to the remote container, deleting any excess
|
||
files in the container.
|
||
|
||
rclone sync --interactive /home/local/directory remote:container
|
||
|
||
### --fast-list
|
||
|
||
This remote supports `--fast-list` which allows you to use fewer
|
||
transactions in exchange for more memory. See the [rclone
|
||
docs](/docs/#fast-list) for more details.
|
||
|
||
### Modification times and hashes
|
||
|
||
The modification time is stored as metadata on the object with the
|
||
`mtime` key. It is stored using RFC3339 Format time with nanosecond
|
||
precision. The metadata is supplied during directory listings so
|
||
there is no performance overhead to using it.
|
||
|
||
If you wish to use the Azure standard `LastModified` time stored on
|
||
the object as the modified time, then use the `--use-server-modtime`
|
||
flag. Note that rclone can't set `LastModified`, so using the
|
||
`--update` flag when syncing is recommended if using
|
||
`--use-server-modtime`.
|
||
|
||
MD5 hashes are stored with blobs. However blobs that were uploaded in
|
||
chunks only have an MD5 if the source remote was capable of MD5
|
||
hashes, e.g. the local disk.
|
||
|
||
### Performance
|
||
|
||
When uploading large files, increasing the value of
|
||
`--azureblob-upload-concurrency` will increase performance at the cost
|
||
of using more memory. The default of 16 is set quite conservatively to
|
||
use less memory. It maybe be necessary raise it to 64 or higher to
|
||
fully utilize a 1 GBit/s link with a single file transfer.
|
||
|
||
### Restricted filename characters
|
||
|
||
In addition to the [default restricted characters set](/overview/#restricted-characters)
|
||
the following characters are also replaced:
|
||
|
||
| Character | Value | Replacement |
|
||
| --------- |:-----:|:-----------:|
|
||
| / | 0x2F | / |
|
||
| \ | 0x5C | \ |
|
||
|
||
File names can also not end with the following characters.
|
||
These only get replaced if they are the last character in the name:
|
||
|
||
| Character | Value | Replacement |
|
||
| --------- |:-----:|:-----------:|
|
||
| . | 0x2E | . |
|
||
|
||
Invalid UTF-8 bytes will also be [replaced](/overview/#invalid-utf8),
|
||
as they can't be used in JSON strings.
|
||
|
||
### Authentication {#authentication}
|
||
|
||
There are a number of ways of supplying credentials for Azure Blob
|
||
Storage. Rclone tries them in the order of the sections below.
|
||
|
||
#### Env Auth
|
||
|
||
If the `env_auth` config parameter is `true` then rclone will pull
|
||
credentials from the environment or runtime.
|
||
|
||
It tries these authentication methods in this order:
|
||
|
||
1. Environment Variables
|
||
2. Managed Service Identity Credentials
|
||
3. Azure CLI credentials (as used by the az tool)
|
||
|
||
These are described in the following sections
|
||
|
||
##### Env Auth: 1. Environment Variables
|
||
|
||
If `env_auth` is set and environment variables are present rclone
|
||
authenticates a service principal with a secret or certificate, or a
|
||
user with a password, depending on which environment variable are set.
|
||
It reads configuration from these variables, in the following order:
|
||
|
||
1. Service principal with client secret
|
||
- `AZURE_TENANT_ID`: ID of the service principal's tenant. Also called its "directory" ID.
|
||
- `AZURE_CLIENT_ID`: the service principal's client ID
|
||
- `AZURE_CLIENT_SECRET`: one of the service principal's client secrets
|
||
2. Service principal with certificate
|
||
- `AZURE_TENANT_ID`: ID of the service principal's tenant. Also called its "directory" ID.
|
||
- `AZURE_CLIENT_ID`: the service principal's client ID
|
||
- `AZURE_CLIENT_CERTIFICATE_PATH`: path to a PEM or PKCS12 certificate file including the private key.
|
||
- `AZURE_CLIENT_CERTIFICATE_PASSWORD`: (optional) password for the certificate file.
|
||
- `AZURE_CLIENT_SEND_CERTIFICATE_CHAIN`: (optional) Specifies whether an authentication request will include an x5c header to support subject name / issuer based authentication. When set to "true" or "1", authentication requests include the x5c header.
|
||
3. User with username and password
|
||
- `AZURE_TENANT_ID`: (optional) tenant to authenticate in. Defaults to "organizations".
|
||
- `AZURE_CLIENT_ID`: client ID of the application the user will authenticate to
|
||
- `AZURE_USERNAME`: a username (usually an email address)
|
||
- `AZURE_PASSWORD`: the user's password
|
||
4. Workload Identity
|
||
- `AZURE_TENANT_ID`: Tenant to authenticate in.
|
||
- `AZURE_CLIENT_ID`: Client ID of the application the user will authenticate to.
|
||
- `AZURE_FEDERATED_TOKEN_FILE`: Path to projected service account token file.
|
||
- `AZURE_AUTHORITY_HOST`: Authority of an Azure Active Directory endpoint (default: login.microsoftonline.com).
|
||
|
||
|
||
##### Env Auth: 2. Managed Service Identity Credentials
|
||
|
||
When using Managed Service Identity if the VM(SS) on which this
|
||
program is running has a system-assigned identity, it will be used by
|
||
default. If the resource has no system-assigned but exactly one
|
||
user-assigned identity, the user-assigned identity will be used by
|
||
default.
|
||
|
||
If the resource has multiple user-assigned identities you will need to
|
||
unset `env_auth` and set `use_msi` instead. See the [`use_msi`
|
||
section](#use_msi).
|
||
|
||
##### Env Auth: 3. Azure CLI credentials (as used by the az tool)
|
||
|
||
Credentials created with the `az` tool can be picked up using `env_auth`.
|
||
|
||
For example if you were to login with a service principal like this:
|
||
|
||
az login --service-principal -u XXX -p XXX --tenant XXX
|
||
|
||
Then you could access rclone resources like this:
|
||
|
||
rclone lsf :azureblob,env_auth,account=ACCOUNT:CONTAINER
|
||
|
||
Or
|
||
|
||
rclone lsf --azureblob-env-auth --azureblob-account=ACCOUNT :azureblob:CONTAINER
|
||
|
||
Which is analogous to using the `az` tool:
|
||
|
||
az storage blob list --container-name CONTAINER --account-name ACCOUNT --auth-mode login
|
||
|
||
#### Account and Shared Key
|
||
|
||
This is the most straight forward and least flexible way. Just fill
|
||
in the `account` and `key` lines and leave the rest blank.
|
||
|
||
#### SAS URL
|
||
|
||
This can be an account level SAS URL or container level SAS URL.
|
||
|
||
To use it leave `account` and `key` blank and fill in `sas_url`.
|
||
|
||
An account level SAS URL or container level SAS URL can be obtained
|
||
from the Azure portal or the Azure Storage Explorer. To get a
|
||
container level SAS URL right click on a container in the Azure Blob
|
||
explorer in the Azure portal.
|
||
|
||
If you use a container level SAS URL, rclone operations are permitted
|
||
only on a particular container, e.g.
|
||
|
||
rclone ls azureblob:container
|
||
|
||
You can also list the single container from the root. This will only
|
||
show the container specified by the SAS URL.
|
||
|
||
$ rclone lsd azureblob:
|
||
container/
|
||
|
||
Note that you can't see or access any other containers - this will
|
||
fail
|
||
|
||
rclone ls azureblob:othercontainer
|
||
|
||
Container level SAS URLs are useful for temporarily allowing third
|
||
parties access to a single container or putting credentials into an
|
||
untrusted environment such as a CI build server.
|
||
|
||
#### Service principal with client secret
|
||
|
||
If these variables are set, rclone will authenticate with a service principal with a client secret.
|
||
|
||
- `tenant`: ID of the service principal's tenant. Also called its "directory" ID.
|
||
- `client_id`: the service principal's client ID
|
||
- `client_secret`: one of the service principal's client secrets
|
||
|
||
The credentials can also be placed in a file using the
|
||
`service_principal_file` configuration option.
|
||
|
||
#### Service principal with certificate
|
||
|
||
If these variables are set, rclone will authenticate with a service principal with certificate.
|
||
|
||
- `tenant`: ID of the service principal's tenant. Also called its "directory" ID.
|
||
- `client_id`: the service principal's client ID
|
||
- `client_certificate_path`: path to a PEM or PKCS12 certificate file including the private key.
|
||
- `client_certificate_password`: (optional) password for the certificate file.
|
||
- `client_send_certificate_chain`: (optional) Specifies whether an authentication request will include an x5c header to support subject name / issuer based authentication. When set to "true" or "1", authentication requests include the x5c header.
|
||
|
||
**NB** `client_certificate_password` must be obscured - see [rclone obscure](/commands/rclone_obscure/).
|
||
|
||
#### User with username and password
|
||
|
||
If these variables are set, rclone will authenticate with username and password.
|
||
|
||
- `tenant`: (optional) tenant to authenticate in. Defaults to "organizations".
|
||
- `client_id`: client ID of the application the user will authenticate to
|
||
- `username`: a username (usually an email address)
|
||
- `password`: the user's password
|
||
|
||
Microsoft doesn't recommend this kind of authentication, because it's
|
||
less secure than other authentication flows. This method is not
|
||
interactive, so it isn't compatible with any form of multi-factor
|
||
authentication, and the application must already have user or admin
|
||
consent. This credential can only authenticate work and school
|
||
accounts; it can't authenticate Microsoft accounts.
|
||
|
||
**NB** `password` must be obscured - see [rclone obscure](/commands/rclone_obscure/).
|
||
|
||
#### Managed Service Identity Credentials {#use_msi}
|
||
|
||
If `use_msi` is set then managed service identity credentials are
|
||
used. This authentication only works when running in an Azure service.
|
||
`env_auth` needs to be unset to use this.
|
||
|
||
However if you have multiple user identities to choose from these must
|
||
be explicitly specified using exactly one of the `msi_object_id`,
|
||
`msi_client_id`, or `msi_mi_res_id` parameters.
|
||
|
||
If none of `msi_object_id`, `msi_client_id`, or `msi_mi_res_id` is
|
||
set, this is is equivalent to using `env_auth`.
|
||
|
||
#### Anonymous {#anonymous}
|
||
|
||
If you want to access resources with public anonymous access then set
|
||
`account` only. You can do this without making an rclone config:
|
||
|
||
rclone lsf :azureblob,account=ACCOUNT:CONTAINER
|
||
|
||
{{< rem autogenerated options start" - DO NOT EDIT - instead edit fs.RegInfo in backend/azureblob/azureblob.go then run make backenddocs" >}}

||
> azure-principal.json
|
||
|
||
See ["Create an Azure service principal"](https://docs.microsoft.com/en-us/cli/azure/create-an-azure-service-principal-azure-cli) and ["Assign an Azure role for access to blob data"](https://docs.microsoft.com/en-us/azure/storage/common/storage-auth-aad-rbac-cli) pages for more details.
|
||
|
||
It may be more convenient to put the credentials directly into the
|
||
rclone config file under the `client_id`, `tenant` and `client_secret`
|
||
keys instead of setting `service_principal_file`.
|
||
|
||
|
||
Properties:
|
||
|

- Required: false
|
||
|
||
#### --azureblob-use-msi
|
||
|
||
Use a managed service identity to authenticate (only works in Azure).
|
||
|
||
When true, use a [managed service identity](https://docs.microsoft.com/en-us/azure/active-directory/managed-identities-azure-resources/)
|
||
to authenticate to Azure Storage instead of a SAS token or account key.
|
||
|
||
If the VM(SS) on which this program is running has a system-assigned identity, it will
|
||
be used by default. If the resource has no system-assigned but exactly one user-assigned identity,
|
||
the user-assigned identity will be used by default. If the resource has multiple user-assigned
|
||
identities, the identity to use must be explicitly specified using exactly one of the msi_object_id,
|
||
msi_client_id, or msi_mi_res_id parameters.
|
||
|
||
Properties:
|
||
|
||
- Config: use_msi
|
||
- Env Var: RCLONE_AZUREBLOB_USE_MSI
|
||
- Type: bool
|
||
- Default: false
|
||
|
||
#### --azureblob-msi-object-id
|
||
|
||
Object ID of the user-assigned MSI to use, if any.
|
||
|
||
Leave blank if msi_client_id or msi_mi_res_id specified.
|
||
|
||
Properties:
|
||
|
||
- Config: msi_object_id
|
||
- Env Var: RCLONE_AZUREBLOB_MSI_OBJECT_ID
|
||
- Type: string
|
||
- Required: false
|
||
|
||
#### --azureblob-msi-client-id
|
||
|
||
Object ID of the user-assigned MSI to use, if any.
|
||
|
||

#### --azureblob-use-emulator
|
||
|
||
Uses local storage emulator if provided as 'true'.
|
||
|
||
Leave blank if using real azure storage endpoint.
|
||
|
||
Properties:
|
||
|
||
- Config: use_emulator
|

#### --azureblob-endpoint
|
||
|
||
Endpoint for the service.
|

#### --azureblob-upload-cutoff
|
||
|
||
Cutoff for switching to chunked upload (<= 256 MiB) (deprecated).
|
||
|
||
Properties:

||
|
||

- Required: false
|
||
|
||
#### --azureblob-chunk-size
|
||
|
||
Upload chunk size.
|
||
|
||
Note that this is stored in memory and there may be up to
|
||
"--transfers" * "--azureblob-upload-concurrency" chunks stored at once
|
||
in memory.
|
||
|
||
Properties:
|
||
|
||
- Config: chunk_size
|
||
- Env Var: RCLONE_AZUREBLOB_CHUNK_SIZE
|
||
- Type: SizeSuffix
|
||
- Default: 4Mi
|
||
|
||
#### --azureblob-upload-concurrency
|
||
|
||
Concurrency for multipart uploads.
|
||
|
||
This is the number of chunks of the same file that are uploaded
|
||
concurrently.
|
||
|
||
If you are uploading small numbers of large files over high-speed
|
||
links and these uploads do not fully utilize your bandwidth, then
|
||
increasing this may help to speed up the transfers.
|
||
|
||
In tests, upload speed increases almost linearly with upload
|
||
concurrency. For example to fill a gigabit pipe it may be necessary to
|
||
raise this to 64. Note that this will use more memory.
|
||
|
||
Note that chunks are stored in memory and there may be up to
|
||
"--transfers" * "--azureblob-upload-concurrency" chunks stored at once
|
||
in memory.
|
||
|
||
Properties:
|
||
|
||
- Config: upload_concurrency
|
||
- Env Var: RCLONE_AZUREBLOB_UPLOAD_CONCURRENCY
|
||
- Type: int
|
||
- Default: 16
|
||
|
||
#### --azureblob-list-chunk
|
||
|
||
Size of blob list.
|
||
|
||
This sets the number of blobs requested in each listing chunk. Default
|
||
is the maximum, 5000. "List blobs" requests are permitted 2 minutes
|
||
per megabyte to complete. If an operation is taking longer than 2
|
||
minutes per megabyte on average, it will time out (
|
||
[source](https://docs.microsoft.com/en-us/rest/api/storageservices/setting-timeouts-for-blob-service-operations#exceptions-to-default-timeout-interval)
|
||
). This can be used to limit the number of blobs items to return, to
|
||
avoid the time out.
|
||
|
||
Properties:
|
||
|
||
- Config: list_chunk
|
||
- Env Var: RCLONE_AZUREBLOB_LIST_CHUNK
|
||
- Type: int
|
||
- Default: 5000
|
||
|
||
#### --azureblob-access-tier
|
||
|
||
Access tier of blob: hot, cool, cold or archive.
|
||
|
||
Archived blobs can be restored by setting access tier to hot, cool or
|
||
cold. Leave blank if you intend to use default access tier, which is
|
||
set at account level
|
||
|
||
If there is no "access tier" specified, rclone doesn't apply any tier.
|
||
rclone performs "Set Tier" operation on blobs while uploading, if objects
|
||
are not modified, specifying "access tier" to new one will have no effect.
|
||
If blobs are in "archive tier" at remote, trying to perform data transfer
|
||
operations from remote will not be allowed. User should first restore by
|
||
tiering blob to "Hot", "Cool" or "Cold".
|
||
|
||
Properties:
|
||
|
||
- Config: access_tier
|
||
- Env Var: RCLONE_AZUREBLOB_ACCESS_TIER
|
||
- Type: string
|
||
- Required: false
|
||
|
||
#### --azureblob-archive-tier-delete
|
||
|
||
Delete archive tier blobs before overwriting.
|
||
|
||
Archive tier blobs cannot be updated. So without this flag, if you
|
||
attempt to update an archive tier blob, then rclone will produce the
|
||
error:
|
||
|
||
can't update archive tier blob without --azureblob-archive-tier-delete
|
||
|
||
With this flag set then before rclone attempts to overwrite an archive
|
||
tier blob, it will delete the existing blob before uploading its
|
||
replacement. This has the potential for data loss if the upload fails
|
||
(unlike updating a normal blob) and also may cost more since deleting
|
||
archive tier blobs early may be chargable.
|
||
|
||
|
||
Properties:
|
||
|
||
- Config: archive_tier_delete
|
||
- Env Var: RCLONE_AZUREBLOB_ARCHIVE_TIER_DELETE
|
||
- Type: bool
|
||
- Default: false
|
||
|
||
#### --azureblob-disable-checksum
|
||
|
||
Don't store MD5 checksum with object metadata.
|
||
|
||
Normally rclone will calculate the MD5 checksum of the input before
|
||
uploading it so it can add it to metadata on the object. This is great
|
||
for data integrity checking but can cause long delays for large files
|
||
to start uploading.
|
||
|
||
Properties:
|
||
|
||
- Config: disable_checksum
|
||
- Env Var: RCLONE_AZUREBLOB_DISABLE_CHECKSUM
|
||
- Type: bool
|
||
- Default: false
|
||
|

- Default: 1m0s
|
||
|
||
#### --azureblob-memory-pool-use-mmap
|
||
|
||
Whether to use mmap buffers in internal memory pool. (no longer used)
|
||
|
||
Properties:

|
||
|
||
Properties:
|
||
|

|
||
#### --azureblob-public-access
|
||
|
||
Public access level of a container: blob or container.
|
||
|
||
Properties:
|
||
|
||
- Config: public_access
|
||
- Env Var: RCLONE_AZUREBLOB_PUBLIC_ACCESS
|
||
- Type: string
|
||
- Required: false
|
||
- Examples:
|
||
- ""
|
||
- The container and its blobs can be accessed only with an authorized request.
|
||
- It's a default value.
|
||
- "blob"
|
||
- Blob data within this container can be read via anonymous request.
|
||
- "container"
|
||
- Allow full public read access for container and blob data.
|
||
|
||
#### --azureblob-directory-markers
|
||
|
||
Upload an empty object with a trailing slash when a new directory is created
|
||
|
||
Empty folders are unsupported for bucket based remotes, this option
|
||
creates an empty object ending with "/", to persist the folder.
|
||
|
||
This object also has the metadata "hdi_isfolder = true" to conform to
|
||
the Microsoft standard.
|
||
|
||
|
||
Properties:
|
||
|
||
- Config: directory_markers
|
||
- Env Var: RCLONE_AZUREBLOB_DIRECTORY_MARKERS
|
||
- Type: bool
|
||
- Default: false
|
||
|
||
#### --azureblob-no-check-container
|
||
|
||
If set, don't attempt to check the container exists or create it.
|
||
|
||
This can be useful when trying to minimise the number of transactions
|
||
rclone does if you know the container exists already.
|
||
|
||
|
||
Properties:
|
||
|
||
- Config: no_check_container

|
||
|
||
#### --azureblob-delete-snapshots
|
||
|
||
Set to specify how to deal with snapshots on blob deletion.
|
||
|
||
Properties:
|
||
|
||
- Config: delete_snapshots
|
||
- Env Var: RCLONE_AZUREBLOB_DELETE_SNAPSHOTS
|
||
- Type: string
|

- Required: false
|
||
- Choices:
|
||
- ""
|
||
- By default, the delete operation fails if a blob has snapshots
|
||
- "include"
|
||
- Specify 'include' to remove the root blob and all its snapshots
|
||
- "only"
|
||
- Specify 'only' to remove only the snapshots but keep the root blob.
|
||
|
||
#### --azureblob-description
|
||
|
||

|
||
### Custom upload headers
|
||
|
||
You can set custom upload headers with the `--header-upload` flag.
|
||
|
||
- Cache-Control
|
||
- Content-Disposition
|
||
- Content-Encoding
|
||
- Content-Language
|
||
- Content-Type
|
||
|
||
Eg `--header-upload "Content-Type: text/potato"`
|
||
|
||
## Limitations
|
||
|
||
MD5 sums are only uploaded with chunked files if the source has an MD5
|
||
sum. This will always be the case for a local to azure copy.
|
||
|
||
`rclone about` is not supported by the Microsoft Azure Blob storage backend. Backends without
|
||
this capability cannot determine free space for an rclone mount or
|
||
use policy `mfs` (most free space) as a member of an rclone union
|
||
remote.
|
||
|
||
See [List of backends that do not support rclone about](https://rclone.org/overview/#optional-features) and [rclone about](https://rclone.org/commands/rclone_about/)
|
||
|
||
## Azure Storage Emulator Support
|
||
|
||
You can run rclone with the storage emulator (usually _azurite_).
|
||
|
||
To do this, just set up a new remote with `rclone config` following
|
||
the instructions in the introduction and set `use_emulator` in the
|
||
advanced settings as `true`. You do not need to provide a default
|
||
account name nor an account key. But you can override them in the
|
||
`account` and `key` options. (Prior to v1.61 they were hard coded to
|
||
_azurite_'s `devstoreaccount1`.)
|
||
|
||
Also, if you want to access a storage emulator instance running on a
|
||
different machine, you can override the `endpoint` parameter in the
|
||
advanced settings, setting it to
|
||
`http(s)://<host>:<port>/devstoreaccount1`
|
||
(e.g. `http://10.254.2.5:10000/devstoreaccount1`).
